An efficient co-operative Ni/Cu system for Cadiot–Chodkiewicz coupling utilizes CaC2 as the alkyne source. The advantage of this cross-coupling reaction lies in the low cost of using cheap and readily available raw materials and the simplicity of operation. A series of functionalized diaryl, aryl-alkyl, and aryl-heteroaryl 1,3-diynes are obtained in moderate to high yields.

Herein we have elucidated unusual and unique nucleophilic conjugate 1,3-addition reactions of surveyed oligoynoates toward phosphines through spectroscopic and single crystal X-ray diffraction analyses of three-component reaction products of oligoynoates, phosphines and aldehydes.
